l SPECIFICATION frming part of Letters Patent No. 402,014, dated April 23, 1889.

Application filed July 9, 1888. Serial No. 279,423. (No model.)

T all whom if may concern.-

Be it known that I, Louis GoDDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Clutches, of which the following description,

in connection with the accompanying drawings, is aspeciiication, like letterson the drawings representing like parts.

This invention relates to clutch mechanism 1o of that class in which a loose pulley is moved longitudinally on a shaft, and has for its object Ato improve the construction of the same, whereby the Wear upon the pulley and shaft is largely obviated.

'15 In accordance with my invention the loose pulley is 4mounted on a sleeve free to rotate on the shaft, the said sleeve being provided with a collar or flange, and preferably With a Washer, Which abuts against the said collar or 2o flange, andl against which the shipper lever or rod bears when the said lever or rod (herein vshown as Wedge-shaped) is acted upon to move the loose pulley on the sleeve.

My invention therefore consists, essentially,

- in a shaft and a friction-disk thereon, combined with a free or disconnected sleeve loose on said shaft and capable of a longitudinal and rotary movement thereon, a pulley loose on said sleeve, and means to move the pulley ,3o longitudinally on the sleeve, substantially as and for the purpose specified.

Figure l is a vertical section of a clutch mechanism embodyingmy invention; Fig. 2, an velevation of the Wedge lever or rod and its (3o-operating hub, lshowing the Wedgelever disengaged'from the hub; Fig. 3, an elevation of the Wedge-lever and hub, with the Wedge in engagement with the hub; Figs. 4l and 5, details to be referred to.

The shaft a, supported in a frame, a', has firmly secured to it a friction-disk, a2, provided, as shown, with a friction-surface, a3, preferably of leather.

The shaft a has loosely mounted on it a sleeve, d4, provided With a ycollar or flange, a5, the said sleeve being free and disconnected and capable of longitudinal and rotary movement on the shaft. The sleeve a4 has loosely mounted on it a pulley, b, having its hub b made, as herein shown, of substantially the 5o same length as the said sleeve, the said hub having mounted on it a collar or hub, b2, provided with flanges b3 on its opposite sides, the said flanges being made inclined foraportion of their length, to form, With a Washer, b4, on 5 5 the sleeve a4, (but which may be the flange ci) a Wedge-shaped opening, into which the Wedge-shaped forks h6 of a shipper-rod, t7, areadapted to be drawn or moved when it is desired to bring the periphery lor rim of the loose pulley into engagement with the friction-'surface of the disk a2 to impart rotation to the shaft, the loose pulley being driven in usual manner by a belt. I(N ot shown.) The hub of the pulleynear the disk a2 has loosely 65 mounted on it a collar, c, having secured to it, as herein shown, rods c, adapted to enter holes c2 in the said disk, the said rods being encircled by springs c3, Which act to disengage the pulley from the disk a2 when the 7o pressure upon the hub b3 and pulley b is WithdraWn-that is, When the Wedge-shaped shipper-rod l)T is in the position shown in Figs. 1 and 2. Vith the parts in the position shown in Ftg. l,th'e pulley is free to run on the sleeve 75 a4 Without imparting rotation to the shaft.

To rotate the shaft, the shipper-rod is drawn or moved from the position shown in Fig. 2 to that shown in Fig. 3, the Wedge-forks acting on the inclined part of the iianges and 8o against the Washer to move the pulley longiltudinally over the sleeve into engagement with the friction-disk. lWhen the pulley is disengaged from the friction-disk, it is free to run on the sleeve and the latter free to run on the shaft, thereby diminishing the Wear on the pulley and shaft, the Wear falling principally on the sleeve, which maybe easily replaced by another When Worn.

I claim 1 A shaft and a friction-disk thereon, combined with a free and disconnected sleeve loose on said shaft and capable of longitudinal and rotary movement on said shaft, a pulley loose on said sleeve, and means to move In testimony whereof lhave signedmynzune |o 'j the pulley longitudinally on the sleeve, subto this speeiieation in thepresenee of two substantially as and foiI the purpose specied. seribing witnesses.
